What are some common problems with GE microwaves?

Some common problems with GE microwaves include not heating, turntable not turning, and door not closing properly, similar to other microwave brands but with decent parts availability. First, microwave not heating food but runs and light works due to magnetron failed after 5 to 7 years costing 50 to 100 dollars for part that generates microwaves, or high voltage diode failed at 10 to 20 dollars, or high voltage capacitor failed at 15 to 30 dollars, or door switch failed that prevents magnetron from powering if door not sensed closed, testing requires discharge of capacitor which stores lethal voltage, so call technician. Second, turntable not turning due to turntable motor failed at 15 to 30 dollars or turntable coupler cracked that connects motor to glass tray, replace motor and coupler. Third, door not latching or not closing due to door latch or hook broken at 20 to 40 dollars from slamming door, causing microwave to not start as safety interlock prevents operation if door open. Fourth, loud buzzing or humming noise during operation due to magnetron failing or high voltage transformer failing. Fifth, control panel buttons not working due to touchpad failure at 40 to 80 dollars from moisture. Sixth, sparking inside due to food splatter on waveguide cover, clean cover. To prevent problems, clean interior weekly, do not run empty, and avoid slamming door.
